Hello Guys,

I'm new to the world of FreeNas and i have a problem/question.

Is there any guide that i can follow to do so?

Can you help?

Best regards,

That´s the error.

You cannot set a quota to an amount less than is currently being used by a dataset. What you can do is create a new dataset with the desired size, copy the data to it and destroy the old dataset.

One tip: I have made it a habbit to set the quota for my datasets to "0". That way they can grow untill I am running out of space on my pool. I did it this way because I am not sure which of my datasets would grow the most or the fastest.

Configuring it that way will allow you to take space from that dataset as well?

By the way, to delete a Dataset what do i need to "stop" or unmount?

Doing it that way, your dataset does not have a predefined size. It get space as long as that is available within in you storage.

Ok i will do so

Thanks once again

Before you destroy your dataset you should try if you can set the quota to 0. Never done that but it might work. If not, you can simply delete it within the GUI. See chapter 9.1.10 in the user manual. If you have shares on that dataset already I think you should delete those first.

One final thing. Please, if you need to post more questions on the forum read the guidelines for posting. There are a lot of members willing to help but they need to know some basic things about your systems hardware and software to help you find adequate answers.

You can't redefine the quota unfortunatly.

Do you know where can i find those guidelines?

Thanks.
